Deep well water supply reaching further than standard bore pumps can manage is the CJ750's DW32-20 injector territory. This is the deepest-reaching option in the model's line-up, working productively past 45 m suction where most siblings have already stopped.
Maximum head is 76 m, with flow starting at 63 L/Min at 10 m suction and continuing to deliver 7 L/Min at 45 m suction depth and 41 m of head. The 1.5 kW / 240V motor draws 9.7 Amps through 50 mm suction and 40 mm discharge pipework, supporting demanding depth requirements.
The thermoplastic injector sits down the bore rather than at the pump. Its smooth bore limits turbulence, and the injector resists salt, hardness and iron. The jet and venturi are matched to bore yield. An optional Offset Flange (101431, 1½ x 1½ inch female thread) allows installation away from the bore to access water above flood level or closer to electricity.
The pump features a cast iron body, stainless steel shaft, double race bearings and a carbon ceramic mechanical seal. The TEFC motor includes thermal overload protection and handles liquid temperatures up to 65°C. Supplied with the WK-CJ30-50 water kit assembled and glued, including a 35 litre tank with 11.7 litre draw-off. Backed by a 2-year warranty; loss-of-prime switch optional.
